Preferably, a crop for silage should be immediately ensiled after harvesting. However, this is not always possible in research situations when a large number of laboratory-scale silos have to be prepared. Thus, in many cases the chopped material is frozen and ensiled at a later date after defrosting. Richard and Allen (1992) and Nelson and Bozich (1996) have shown that freezing vegetative material may increase cell-wall contents, which in turn, may affect nutritive value. The current study was conducted to determine changes in the composition of fresh and frozen stover, ensiled with and without a cell-wall degrading enzyme solution.
